E.g. I have three lists:

L1:=[1,2,3];

K1:=[4,5,6,7,8];

K2:=[7,8,9,10,11];

and if needed I have a fourth list

ALL:=[L1,K1,K2];

Now I´d like to add 99 to all lists whose name contains a 1 and add a 999 to all lists whose name contains a K.

The problem is, when I refer to the elements of ALL, Maple "thinks" I refer to the list. But how do I tell Maple,

that I want to refer to the lists´ name instead of the list itself ...

i'm working on a short program to put random points on a sphere , but i have some difficulties :
 i consider a sphere  where  i choose  n  points  with  "randpoint" then i plot it but it doesn't work if someone can help me to correct my program

here is the program :

>with(geom3d):
> with(plots):
> s2:=sphere(s3,x^2+y^2+z^2=1):
> sphere1:=(x,y,z,R)->[x+R*cos(phi)*cos(theta),y+R*cos(phi)*sin(theta),z+R*sin(phi)]:

Hi!

I have a serious problem and im looking forward to any suggestions.

Like i already wrote i wanna create a simple matrix (14x14) out of four matrices(7x7) and i have no clue how to accomplish this task in maple.

to be more specific, i want to create matrix M=(A,B,C,D) each of them is another 7x7 which results in a 14x14 matrix.

I guess its a simple task but i tried hard and didnt get it worked.

thank you  in anticipation

Dear MaplePrimers,

The y-axis of my graphs consists of small values (<10^(-4)). Unfortunately, Maple displays a lot of numbers after the comma and it's not cool. Is there a command or option that allows to control the numeric formatting (scientific, engineering...) of a particular axis? Specifically, I need to change the decimal formatting to scientific notation. The x-axis is OK and not must be changed.

Regards,

Tuti.

Is there a way of exporting a maplet programme into a universal programme so anyone can access it (someone who does not run maple)?

Thanks in advance

What has happened to the TA forum? Are questions now deliberately mixed with those for Maple? Is it possible to filter and somehow recover the TA forum?

Many thanks

I'm trying to plot multiple inequality conditions such as

n/2 < m < 6-n  if 0 < n < 1/2

and

m >= n/2 if 1/2 < n < 3 .

I tried to do it by creating two plots via inequal and then using "display", which is what Tadashiito did here:

http://www.mapleprimes.com/questions/37286-Plotting-Multiple...

Hello,

I cannot understand the behavior of complexplot in the following...

Suppose you do the following:

> f := (x,y) -> sin(x+I);
> g := (x,y) -> cos(x+I);
> complexplot([f(x,y), g(x,y)],x=-2..2,y=-2..2,color=[red,green]);

This will plot two functions in red and green respectively.

Now, I redefine the functions to return a constant:

> f := (x,y) -> sin(I);

There is a proper function of Maple to perform matrix left division?
This procedure is right for the calculation of the uncertainties of the coefficients?
There are large these uncertainties?
Comment?

My question is this: 

In with(DifferentialGeometry): with(JetCalculus) with(Physics):

I work with the following Jet Bundle:

DGsetup([x], [u, psi], E, 40), 

where psi is declared anticommuting with Setup(anticommutativeprefix={psi}). 

When I work with expressions that are differential polynomials in u with coefficients arbitrary functions of u, the EulerLagrange operator behaves correctly. The same is true if I multiply these expressions by psi or by psi_1 ...

Let

    G:=s->q(1-ps)^(-1)

be a generating function with 1-p=q in (0,1). Then the repeated function composition

    G(G(G(s)));(G@@3)(s);simplify(%);

gives me some concrete expression. What is the simplest way to get the general expression for 3 replaced by n?   

I am recently new to maple software, but I was wondering if someone was able to help me with the following question.

I am trying to plot a 3D graph of some function f(x,y,z), I want a contour type-graph with normal axis, and I also have a few points that I want to plot on that graph:  [x1,y1,z1], ... [xn,yn,zn]; how do I do this on a single graph?

thanks so much;

How to change this general form to solve :

How to calculate with Maple Fourier coefficients on some numerical valued functions and how to calculate and plot the 3 partial sums :

Function B : on the interval [-phi, phi]

f(x)= NUMERICAL (x – phi/2) + NUMERICAL (x+phi/2)

Function C : on the interval [-phi, phi]

f(x) =  NUMERICAL (x+phi/2)

I enclose Maple general solution to the PDF heat equation in 1 dimention.

I need corrections of it to enable me to calculate the heat equation in certain conditions :

 du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

I have 3 different arrays. is there any way that I can put these 3 arrays in one table with a proper heading above each column?

Thanks
